1. INTRODUCTION The series of panel instruments is a versatile, cost effective solution to a wide variety of monitoring and control applications. These instruments are easily set to produce an accurate display of frequency, rate, total, period, time interval, phase, position , flow, etc. Front panel pushbutton or RS-232/RS-485 setup allows the user to customize the unit for a specific application. Digital scaling of zero and span provides direct readout in engineering units.
2. RECEIVING AND UNPACKING Your meter was carefully tested and inspected prior to shipment. Should the meter be damaged in shipment, notify the freight carrier immediately. In the event the meter is not configured as ordered or the unit is inoperable, return the unit to the place of purchase for repair or replacement. Please include a detailed description of the problem. 3.

The input signal voltage must exceed the high and low threshold per the following table or the meter will not operate properly.
11.3 MODES OF OPERATION Input Arm Signal Gate Internal Clk The measurement starts with an input signal transition in one direction and ends, after the expiration of the selected gate time, with the next input signal transition in the same direction such that the conversion time or period is measured over an integral number of input cycles. The internal Start signal ARMS the gate circuit so that the next input signal transition actually OPENS the gate.
Relay #3 energizes and the cycle repeats. As an option, the cycle can be reset from an external signal FUNCTION RESET. The GATETIME is not used and Relay #1 remains de-energized until the FUNCTION RESET external input is grounded for a minimum of 3.33 mS. Sometime during that period, the Batch Total is reset and Relay #1 is energized. The Batch Total is displayed as Item #1 and may be configured to count up from 0 to the preset value, or to count down from the preset value to 0.
RATE AxB is the same as Rate A+B except that A is multiplied by B. RATE A/B (Ratio) is the same as Rate A+B except that A is divided by B. Rate A and B may be scaled such that the ratio of A/B is 1. When the value of B increases the ratio is a number less than 1 and when it decreases the number is greater than 1. RATE A/B-1 (Draw) is the same as Rate A/B (Ratio) except that 1 is subtracted from the ratio to give a zero value when the ratio of the 2 inputs is 1.
TOTAL A-B UPDN is the same as Total A, Total B except that Total A is displayed as item 2, Total B is displayed as item 3 and the difference of A minus B is displayed as item 1. Decimal point 1 applies to both A and B and decimal point 2 applies to the sum of A and B. The resolution of the sum is determined by setting the multiplier (Resolution) from .00001 to 100000. BURST measures the frequency of a burst of pulses from channel A as item 2, and total number of bursts as item 1.
is a number less than 1 and when it decreases the number is greater than 1. 11.7 TIME INTERVAL TIME INTERVAL A TO B measures time between an input on channel A and an input on channel B. Time measurement starts when a pulse is applied to channel A (positive edge if slope A is 0, negative edge if slope A is 1) and the measurement ends when a pulse is received on channel B (positive edge if slope B is 0, negative edge if slope B is 1).

the preset value, or to count down from the preset value to 0. The preset value is placed in Setpoint 1 and the Batch Total is the total with Scale1 and decimal point1 applied. In the Batch mode, Scale1 is set to a positive value to count up and a negative value to count down. Offset1 is set to zero when counting up and to the preset value when counting down. The Grand Total is kept as Item #2.

13.2 QUADRATURE DECODING The quadrature decoder board generates up(+) and down(-) counts that are arithmetically totalized on the main counter board and then displayed. The decoder board has input circuitry that may be jumpered for either single-ended input signals or balanced line driver signals. It will accept the normal A & B quadrature signals and, if present, a zero index signal.
The zero index channel contains the same digital filtering that is provided for the A & B channels. It contains a Polarity jumper that allows selection of either a positive or negative zero index signal. It also contains two Control inputs, C1 and C2 that control the ANDing of the zero index signal with the Channel A and Channel B signals. See “Zero Index Setup” below. The Item indicator light (center right) may be used to determine the location of the Zero Index.
13.3 ZERO INDEX SETUP The relationship between the zero index correction signal and the Channels A & B signals varies with different encoder model numbers and different manufacturers. To accommodate this variation, the Quadrature board has control jumpers and selectable outputs that provide ANDing of the zero index signal with all possible combinations of the Channel A & B signals. Consider a typical encoder model that produces the waveforms shown below. Assume X4 counting is selected.
between counting up and counting down. There are 2 control signals, C1 and C2, and 3 outputs, ZI, ZIX and ZIY that may be jumpered to provide 8 selections of ANDed signals or the zero index signal without ANDing.
counter=0 and the correction=0. The position of the encoder when the counter is reset is not critical. 8. Rotate the optical encoder past the zero index point to set the internal correction. 9. Return to the desired zero mechanical position and verify a zero reading. This completes the procedure. If the encoder is rotated back to mechanical zero, it should read zero.
used here, remove jumper c of E10 that was placed for the test in A. above. C. From the manufacture's specifications for the encoder, determine the number of cycles per revolution. Multiply this by 1, 2, or 4 depending on the selection of X1, X2 or X4 counting and multiply that result by the counter scale factor. Put the final result in the counter Menu item, PULSES. 5. Finally, follow the procedure outlined above under the heading titled, MECHANICAL ZERO. 13.

Using quadrature to determine rate not only has the advantage of displaying direction but also eliminates errors due to vibration and jitter that cause erroneous readings in standard rate meters. The meter uses A-B to display quadrature rate.

If totals are saved on power down, totals are reset to the saved value, otherwise totals are set to zero or to the offset value if offset is not zero.
20. CALIBRATION All ranges of the meter have been digitally calibrated at the factory prior to shipment. The calibration equipment is certified to NIST standards. Calibration constants are stored in nonvolatile memory in EEPROM on the main board , the V-to-Fsignal conditioner and on the analog output board. The crystal on the main board is calibrated via the menu item "calib". Using an accurate, known frequency, the meter is calibrated by entering the error of the in parts per million.

Up to 240 data points may be entered into a test file with one set of values equivalent to input signal and the second set of values the desired display at that input. Deviation Either alarm may operate in the deviation mode. In the menu item "deviation", a value is entered equivalent to the amount above and below the setpoint at which the alarm operates.
Phase Angle In this mode, the meter determines the phase angle between the signals on Channel A and Channel B. The phase angle is measured from 0 to 360 degrees Pulses The menu item pulses is used to set the number of pulses generated by a quadrature encoder for each zero index pulse. The setting is equal to the number of pulses per revolution of the encoder (times 2 or 4 if the count by 2 or 4 is selected on the signal conditioner) times the scale factor.
